TECHNICAL FIELD
[0001] The utility model relates to air compressor waste heat recovery technical field especially relates to a kind of air compressor waste heat recovery equipment. BACKGROUND
[0002] In the industrial field, air compressor is indispensable equipment for many production processes. However, in the process of compressed air, a large amount of electrical energy is converted into heat energy and dissipated in the form of waste heat, which is usually directly discharged into the environment, causing significant energy waste. According to estimates, waste heat generated during air compressor operation accounts for about 80% to 90% of total input electrical energy, and if this heat can be effectively recovered, energy utilization efficiency can be greatly improved.
[0003] However, traditional waste heat recovery devices often use simple straight-tube or plate heat exchanger designs, which results in a small actual effective heat exchange area. Due to insufficient contact area, the process of transferring heat from the heat source (such as the compressor head) to the medium (such as water) that needs to be heated is not sufficient, resulting in low overall heat transfer efficiency.
[0004] In early designs, the heat transfer path is relatively simple and direct, lacking effective optimization of the fluid flow path. For example, in a straight-tube heat exchanger, water flows quickly and has a short contact time with the heat source, making it difficult to fully absorb heat; while overly complex paths can increase flow resistance, affecting system performance. SUMMARY

[0020] Embodiment: a kind of air compressor waste heat recovery equipment, as shown in Figures 1-3 The utility model discloses an air compressor waste heat recovery equipment, which comprises an air compressor body 1, a compressor head 2, a heat exchange box 3, a partition 4, heat exchange plates 5, conveying pipes 6, heat exchange pipes 7, filter screens 8, a water storage tank 9 and a water pump 10. The compressor head 2 is installed at the top of the air compressor body 1. The heat exchange box 3 is installed outside the compressor head 2 by bolts. The heat exchange box 3 is divided into left and right two chambers by the partition 4 connected in the middle. The heat exchange plates 5 are arranged at equal intervals in the heat exchange box 3. The heat exchange plates 5 penetrate through the partition 4, and the right ends of the heat exchange plates 5 are tightly wrapped around the outside of the compressor head 2 to effectively absorb the heat generated in the compression process. The heat exchange pipes 7 designed as multiple bending paths are installed in the left chamber of the heat exchange box 3. The heat exchange pipes 7 are in close contact with the heat exchange plates 5, increasing the contact area between the heat exchange pipes 7 and the heat exchange plates 5, thereby improving the heat transfer efficiency. The upper ends of the heat exchange pipes 7 penetrate through the top of the heat exchange box 3, and the conveying pipes 6 are connected and communicated between the upper ends of the heat exchange pipes 7. The water storage tank 9 is installed at the bottom left of the heat exchange box 3 by bolts. A water outlet groove is formed at the top left of the water storage tank 9. The lower ends of the heat exchange pipes 7 penetrate through the bottom of the heat exchange box 3 and are aligned with the water outlet groove, so that the water after heat exchange can flow into the water storage tank 9. The filter screen 8 is connected to the water outlet groove to filter the impurities in the water flowing into the water storage tank 9 from the heat exchange pipes 7. During the maintenance of the equipment, the water storage tank 9 can be removed for cleaning of the filter screen 8. The water pump 10 is installed at the left side of the water storage tank 9. The right end of the pipe of the water pump 10 is connected to and communicates with the water storage tank 9, so as to pump the preheated water out of the water storage tank 9 for subsequent use.
[0021] In the air compressor body 1 operation process, the compressor head 2 will produce heat. The heat exchange box 3 is provided outside the compressor head 2, and the heat is absorbed by the plurality of heat exchange plates 5, and then the heat is transmitted to the heat exchange pipes 7 in the left chamber. In order to make full use of the heat, the delivery pipe 6 can be connected to the water supply channel, so that the water source is transported into the plurality of heat exchange pipes 7 through the delivery pipe 6, and the heat exchange is realized by contacting the heat exchange plates 5. The heated water is filtered by the filter screen 8 and then stored in the water storage tank 9. The user can connect the water equipment to the pipe at the left end of the water pump 10, and start the water pump 10, so as to pump the heated and filtered water to the water equipment for use. In this way, the effective use of the heat which would be wasted is realized, and the energy consumption is reduced. The design of the plurality of heat exchange plates 5 and the heat exchange pipes 7 significantly improves the heat collection efficiency.
[0022] As shown in Figure 1 , Figure 2 and Figure 4 , it also includes a rotating plate 11, a movable plate 12, a sewage valve 13, a connecting pipe 14 and a high-pressure nozzle 15. The rotating plate 11 is rotatably connected to the top left side of the heat exchange box 3. The movable plate 12 is rotatably connected to the top right side of the heat exchange box 3. The sewage valve 13 is installed at the lower left rear of the heat exchange box 3, and is communicated with the left chamber inside the heat exchange box 3, so as to facilitate the discharge of internal sewage. The movable plate 12 and the rotating plate 11 are both provided with safety locks to ensure that they cannot be opened without authorization. The connecting pipe 14 is rotatably connected to the upper left side of the heat exchange box 3, and a plurality of high-pressure nozzles 15 are installed on the connecting pipe 14 at intervals. The high-pressure nozzles 15 are distributed in the left chamber, which can effectively clean the dust on the surface of the heat exchange pipes 7 and the heat exchange plates 5.
[0023] As shown in Figure 4 , in order to realize the automatic cleaning process, the device also includes a full gear 16, a torsion spring 17, a motor 18 and a missing gear 19. The full gear 16 is welded to the front end of the connecting pipe 14. The torsion spring 17 is connected between the full gear 16 and the heat exchange box 3 and is sleeved outside the connecting pipe 14. The motor 18 is installed on the front side of the heat exchange box 3 near the connecting pipe 14 by bolts. The output shaft of the motor 18 is connected with the missing gear 19 which is engaged with the full gear 16. Thus, the rotation of the connecting pipe 14 and the high-pressure nozzles 15 can be realized by driving the motor 18, so as to achieve the purpose of automatic cleaning.
[0024] When the internal structure needs to be overhauled or cleaned after the device is used for a long time, the rotating plate 11 and the movable plate 12 can be opened to facilitate operation. Although the rotating plate 11 and the movable plate 12 provide protection for the heat exchange box 3, over time, the heat exchange plates 5 and the surfaces of the heat exchange pipes 7 can still be contaminated with dust and other impurities, which can affect heat conduction. At this time, an external water pipe can be connected to the connecting pipe 14, so that clean water flows into the connecting pipe 14 and is sprayed out through the high-pressure spray head 15. At the same time, the motor 18 is started, and the output shaft rotates to drive the cogwheel 19 to rotate. When the toothed part of the cogwheel 19 engages with the gear wheel 16, it will drive the gear wheel 16 and the connecting pipe 14 to rotate, so that the high-pressure spray head 15 rotates with it. The torsion spring 17 deforms. Once the cogwheel 19 disengages from the gear wheel 16, the torsion spring 17 will make the gear wheel 16, the connecting pipe 14 and the high-pressure spray head 15 reverse and reset. Through the continuous operation of the motor 18 and the action of the torsion spring 17, the connecting pipe 14 and the high-pressure spray head 15 can repeatedly swing, effectively flushing the dust on the surfaces of the heat exchange plates 5 and the heat exchange pipes 7 in the left chamber of the heat exchange box 3. After flushing, open the sewage valve 13 to drain the sewage in the chamber. For the heat exchange plates 5 in the right chamber, since they are inserted on the compressor head 2, the operator only needs to perform simple wiping during cleaning. After completing the cleaning process, turn off the water source and stop the motor 18 from running.
